On your shopping and preparing?
I have a few presents bought for children in the family already, makes it feel less stressy / expensive nearer the time and I can then enjoy the atmosphere and build up. It's getting harder to buy early for DCs as they will change their minds if I ask them now. But nearer the time you run the risk of popular toys being sold out. Luckily we seem to have skipped / not been interested in most fads including Buzz Lightyear, DS and the blooming hamsters.
No doubt Xmas adverts will be starting (have started??) soon and the interest brainwashing will start.
